The Crimson Trace Smith and Wesson Lasergrips for M and P with Red Laser are interchangeable between different calibers of the M and P pistol and feature a hard polymer surface that's most closely matches the medium stock Smith and Wesson grip inserts. These lasergrips fit the M and P pistol just like the stock grips while offering a compact laser diode housing that's well suited to most carry and duty holsters. They also feature a rear-activation switch that's part of your natural grip so there's no fumbling to activate the laser with your trigger finger.
